Be it known that LEDWARD DUMPELMANN, of the city of Washington, and District of Columbia, have invented a new and useful process for disinfecting unwholesome or contagious atmospheric air accumulating in sick and dissecting-rooms, hospitals, ships, sewers, water-closets, etc.; and that the following isa fullel and exact description of my invention; which will enable others skilled in theart to use and repeat My invention consists in providing any kind of lamp or other vessel with such fluid and co nbusti icals which, when lighted, evolve disinfecting gases, such as chlorine, hypochlorous acid, bromine, bOllO acid, creosote, etc. i

The combustibleliquid which I found particularly convenient and suitable for the, purpose specified, and,

' Ninety grains of perchlcride of copper are dissolved in sufiicient water; upon this solution we pour aniix ture ofhalf a pint ofcommon alcohol,'with one and a half fluid drachm of chloroform. If the odor is not dis-f liked, traces of wood" or coal creosote may be added thereto. a g

These proportions may be altered, and I do not confine myself entirely to the above. 7 a

This mixture, brought into any ordinary spirit-lamp of glass, sheet iron,&c., and lighted, evolves, within a ten minutes time, enough chlorine and creosote vapor to impregnate and disinfect a room sixteen feet high and a twenty by twenty feet wide. So gradual is the evolution of this gas, that the patientsafilicted \vith contagious their beds during the fumigation of their lodgings.

What I claim as my invention, and desire to secure by Letters Patent, isa 1. Disinfecting rooms, ships, water-closets,vand other apartments by burning a. liquid charged with any chloride salt, decomposable at the temperature of a burning flame, as described. l i

2. A liquid for disinfection, being combustible, and containing decomposable volatile chlorides,substantially i as described.
